Status Update

mAEWing1

  • UMN
    • Sköll with WS1 complete, flight attempted on 2015-06-16, but scrubbed due to intermittent faults with ground support equipment.
    • Next Sköll flight attempt will be Tuesday, 2015-06-23.
    • Hati center-body and wing layup with WS2 complete. Wings (WS2) will be built as flexible wings. Anticipating ready for flexible aircraft flights 1st week of July.
  • STI
    • Transitioning from flight data analysis on Fenrir to model development.
    • A structure only Reduced Order Model (ROM) has been built.
    • Anticipating 1 ROM complete next week, linear model at 1 flight condition, likely around when BFF goes unstable.
  • CM Soft
    • Unsteady aeroelastic simulation with the c.g. held fixed.
    • Inviscid flow with a step input.
    • Used to find damping ratio as a function of airspeed.
    • Estimating an 11-14 Hz mode is going unstable at around 78 - 80 knots.
    • Not much variation with altitude.
    • May be useful to look at reactions at the center node.
  • VT
    • Working on a drag buildup.
    • Mostly friction and form drag at our test conditions, low induced drag contributions.
    • Adding contribution from leading edge flaps.
    • Similar to CM Soft, not finding much variation with altitude.
